Florida Comprehensive Pavement Analysis System (COMPAS) - Vol. 2: User's Guide (Prepared for Florida DOT State Project 99000-1712.) (TTI-1991-21)

This report explains the use of the Florida Comprehensive Pavement Analysis System (COMPAS). This system was developed to assist the Florida Department of Transportation in evaluating the effects of different forecasted truck characteristics and truck use on flexible pavement performance and life-cycle costs. The evaluation of the effects of heavy vehicle characteristics is accompl ished through the combined use of the following analytical models in Florida COMPAS: 1. a load-shift algorithm; 2. a vehicle simulation model; 3. a program for evaluating load equivalencies; 4. a program for evaluating cumulative IS-kip ESAL's; 5. a performance evaluation and overlay design procedure; and 6. a cost evaluation program. In order to provide user support in applications of Florida COM PAS , data entry programs have been written to facilitate user input of required data. These programs serve as interfaces between the user, and the various analytical models given previously, and were specifically written to make the package user friendly. A user's guide to this comprehensive pavement analysis system is presented in this report. The general structure of the computer package is explained, the different input data screens are discussed, and separate input guides to the pavement performance, vehicle simulation, and cost analysis models are presented.
